Cetainly true. I rememeber being hit by this once myself and it
was unexpected.

But (in theory) MAKEDEV should be able to check the device major
minor numbers of existing device entries to ensure that they are
correct. I can't see any other reason why MAKEDEV would want to
delete them first unless this was the intention. Of course, doing
that from a shell script would be a little difficult - possible,
but slow.

I only mention this since it has some relevence to other discussion. :-)
